How Much Does A Yellow Onion Weigh?
All onions have almost the same weight range regardless of whether they are yellow, red or white in color. Thus approximately a large, yellow onion would weight seven to eight ounces (at least 225 grams), a medium-sized yellow onion would weigh six ounces (150 grams), and a small-sized yellow onion would weigh four ounces (125 grams).
In this short tutorial, we will be answering How many onions do a yellow onion weigh?a through a thorough breakdown of onion weights at various sizes. Not everybody knows exactly how much an onion weighs in kilograms or ounces. The onion weight differs depending on where it is produced, though the differences in sizes are not that dramatic. The weight of a yellow onion may vary depending on the onion size.
The U.S. Department of Agriculture has a rating system which takes into account onion size, not weight. When determining an onions weight, it is necessary to also consider its density. In addition to weight, diameter is another useful measurement for the size of onions.
In general, a large onion is roughly the size of a one-cup measuring cup, a medium onion will be roughly the size of a one-half-cup measuring cup, and a small onion will be roughly the size of a 1/4-cup measuring cup. As explained by one of our culinary instructors, a medium onion is roughly the size of a baseball, while a large onion is roughly the size of a softball pitched slowly. In our tests, the medium onion produced around 2 cups of onion chips, and a large onion produced 3 cups of those same-sized chips. Since a medium onion yields around a cup of diced onions, you can expect to end up with somewhere between 2-3 cups of onions if sliced.
If your recipe calls for a cup of diced onion, you should feel confident buying a medium-sized onion, which is roughly the size of a navel orange. If you do not have a scale and are left guessing at onion sizes, knowing how many cups of chopped onions are the equivalent of a medium onion is useful. Next time a recipe calls for one cup of chopped onions, you will be more confident knowing how many of each kind you will need.
Recipes often call for one small, medium, or large onion with no guidance on the number of cups of chopped onions that those sizes should produce. When you are cutting onions, you will have to keep in mind that the roughness of the slices, along with their shape, will impact the number of onions you will be able to pack into one cup. In general, if a recipe calls for small onions, they are calling for a standard-sized, 3-5-ounce small onion.
| Types | Weight |
| Yellow Onion | 10 ounces |
| White Onions | 6 ounces |
| Red Onions | 4-6 ounces |
A small onion that is 1 to 2 inches across would weigh about 2.46 ounces (70 grams). A large yellow onion mostly weighs around 8-12 ounces, with 10 ounces being an average weight for a large onion.
For our testing sample, we chose a single medium yellow onion that was between 2 and 3.25 inches in diameter. Onions classified as medium are those that are between 2 and 3.25 inches in diameter. The onions categorized as large are those having their diameter of 3 inches or larger.

Sometimes they will give you a volume amount of onions (2 cups), sometimes a weight (4 ounces), and other times onions are given in the description of production (2 medium Bermuda onions). Red onions, however, cost a little extra, $2.58 for 8 ounces of chopped yellow onions at Wal-Mart. The most common onions are yellow onions, which you are likely to use for French onion soup and other dishes. Brown, or yellow onions, are stronger flavored than the other varieties, making them usable for most dishes.
A medium shallot is only about 1 ounce, which yields about 1/4 cup crushed onions. If a recipe calls for 1 cup finely ground onions, that would require about 3 medium large onions, or if you want larger chopped sizes, then about 2 would work. Like most fruits and vegetables, the amount of onions needed for a 1-cup measurement depends on how finely chopped they are. If a smaller onion is used, you might be looking at smaller portions, and so one may end up not having exactly the number of onions required by the recipe.
If one does not have a scale yet, I would not fret too much; one extra ounce or two of onions will not ruin your soup or meatloaf, or anything else. Using the red grapefruit as your reference for size, you can probably expect that one big onion the same size will produce around 3 cups of onions for whatever you are cooking. If we used our previous reference that one navel orange is the same size as one medium-sized onion, we could then use a smaller red grapefruit as our reference for what the largest onion could be.
If you are the kind of cook that prefers using precise measurements, you will not want to miss our discussion on the onion-size equivalents per cup. In this post, we are going to look at ways to figure out how many onions are in one cup, and also ways to estimate how many onions are in up to 4-cup slices.

Now that we have decoded the centuries-old mystery of what a recipe means when it calls for a particular size onion, you are ready to slice these onions confidently. If it has happened to you that after watching your favourite cooking show, you wanted to cook exactly the same recipe, but were confused by terms such as a dash of salt, or a sliced yellow onion in the right size, then no worries, because we are here to solve that problem of yours, and we are going to explain to you exactly how much does a yellow onion weigh. We were wondering about the very same thing too and did some research in order to know exactly what categorizes a onion as small, medium, or big. To make this accurate, I have to make this weight-based; in order to provide you with instructions, I need to know what, in fact, the big 2 onions, chopped, means.
We would stress these sizes are just estimates, and the vast majority of recipes will work with onion weights in a range. We are not aware of any industry-standard sizes or charts, but according to the Nigellas earlier recipes, the largest onions should be about 225-275g (8-9oz).
A medium onion will be smaller than 225-275g (8-9 ounces) and about 150-170g (about 6 ounces), while a small onion will weigh about 125g (4 1/2 ounces) or less. The average onion is 100 grams, or 3.5 ounces, or around 0.1 kg.
